In a sample that contains hydrogen, among other things, four spectral lines are
found in the infrared with wavelengths 7460 nm, 4654 nm, 4103 nm, and 3741 nm. Which
one does not belong to a hydrogen spectral series?
What lines would be missing for hydrogen in an absorption spectrum? What wavelengths are missing for hydrogen in an emission spectrum?
Suppose the electron in a hydrogen atom moves fron n=2 to n=1. In which region of the electromagnetic spectrum whould you expect the light from this emission to appear? Provide justification for your answer.
